New Delhi, India: An Air India Boeing 787-8 Dreamliner operating flight AI117 from Amritsar to Birmingham experienced an uncommanded deployment of its Ram Air Turbine (RAT) during final approach on October 4, raising fresh concerns over the safety of the carrier’s widebody fleet.
The aircraft, registered VT-ANO, landed safely in Birmingham, though its return service to Delhi was cancelled and the jet was grounded for detailed inspections. India’s aviation regulator, the Directorate General of Civil Aviation (DGCA), has launched a probe into the incident.
According to officials, all electrical and hydraulic systems remained stable despite the RAT deployment. Routine maintenance checks recommended by Boeing were performed on the aircraft, and no discrepancies were reported. The DGCA has stated that the jet will be cleared to return to service only after thorough inspections are completed.
The Federation of Indian Pilots (FIP) President G S Randhawa has formally written to the DGCA, warning that limiting post-crash inspections to fuel control switches is insufficient. Instead, the group has urged regulators to expand checks to the electrical systems of all Boeing 787 aircraft in India.
The FIP highlighted that the aircraft’s Aircraft Health Monitoring (AHM) system flagged a fault in the Bus Power Control Unit (BPCU), which manages the electrical power distribution and may have triggered the RAT deployment. The union stressed that this mirrors deeper systemic issues rather than isolated switch malfunctions.
